MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent N 0. 736.208, dated August11, 1903. Application filed August 27. 1902. Serial No. 121,202. (Nomodel.)

rocate the said scrapers up and down in contact with thecirculating-tubes of the economizer.

In the accompanying drawings, Figure l is a plan view of my improvedmechanical movement. Fig. 2 is an end view looking in the direction ofthe arrow 2, Fig. 1; and Fig. 3 is a side view, partly in section.

A is a frame.

i B is a chain-wheel around which passes a chain extending in thepresent instance to the scrapers of the fuel-economizer.

C is a driving-pulley mounted on a stud A, extending from the frame Aand having a pinion 0 cast on its hub, although it may be made separateand keyed thereto, if desired.

Meshing with the pinion c is a gear-wheel d, secured to a shaft D, whichis mounted in suitable bearings ct a, secured to the frame A. Loose onthe shaft D are two bevel gearwheels E E, having, respectively,clutch-faces e and 6, while keyed to said shaft D is a clutchsleeve D,having clutch-faces d (Z which are arranged to engage with either one ofthe clutch-faces c c. This sleeve D is operated by a lever F, pivoted atf to the frame and having a weight f.

Meshing with the bevel gear-wheels E E is a bevel gear-Wheel G, which iskeyed to a sleeve G, having its bearings in the hub h of a fixedinternal gear-wheel H. This internal gear has lugs h securely fastenedto the frame A.

On the shaft I is an internal gear-Wheel I,

having a greater number of teeth than the internal gear H, and there isa pinion J meshing with the teeth of said wheel H and a pinion J meshingwith the teeth of the Wheel I. These two pinions are loosely coupledtogether by lugs j j, which interlock, as

shown, the said pinions being loose on the sleeve G, which is madeeccentric, one eccentric being greater than the other, so that bothpinions will always mesh with their respective gears, and as theyrevolve one tooth in the present instance will be lost on eachrevolution, so that the shaft I will be driven from the shaft D veryslowly,

On the shaft I is a bevel-pinion I meshing witha bevel gear wheel B onthe chain-wheel B, which in the present instance is part of the castingof the bevel-gear, although they may be arranged independently, ifdesired.

In order to reverse the movement of the scrapers, two lugs l and 2 areprovided on the wheel B, the lug 2 being adjustable in the presentinstance, and the hub of the wheel having two loose arms 3 and 4, thefirst only of which engages the said lugs 1 and 2. The arm 4 has aprojection 5, with which the arm 3 engages, and there is a projection onon a disk M, with which the arm 4: engages. The disk M is loose on theshaft and is connected to a rack-bar N, having rack-teeth a, whichengage with the teeth 12 of a segment P, pivoted at p to the fixedgear-casing H. 011 the segment P are two arms 3 s, which engage thelever F, so as to shift the clutch-sleeve D into gear with either of thebevel-wheels E and E.

The operation of the device is as follows:

movement can be applied to any mechanism Where it is desired to converta quick rotary motion into a slow intermittent rotary motion first inone direction and then in the reverse direction and is especiallyadapted for use in connection with the scrapers of fuel-economizers.

I claim as my invention- 1. The combination in a mechanical movement, ofa driving and a driven shaft, a clutch on one of the shafts, meansconstructed to be actuated through said clutch for operating the othershaft in either direction, means for shifting the clutch, said meansincluding a rack-rod, a gear meshing therewith, and a lever controlledby the gear and operative upon the clutch, substantially as described.

2. The combination of a Wheel 0, a shaft D geared thereto, twobevel-gears on the shaft, a clutch-sleeve between the bevel-gears andarranged to engage either of the same, a bevel gear-wheel common to thesaid gears, ashaft driven from the bevel-gears, reducing-gear betweenthe shaft and the gear whereby the shaft is made to rotate slowly, andmechanism for shifting the clutch-sleeve, substantially as described.

3. The combination in a mechanical movement, of a driven shaft havingtwo bevelgears loosely carried thereon, a sleeve on the shaft arrangedtobe clutched to either bevelgear, a bevel-wheel gearing with both of saidbevel-gears, a sleeve carrying said bevel gearwheel, two eccentrics onthe sleeve, a gearwheel on each eccentric, two internal gear- Wheels,one having a greater number of teeth than the other, one of saidgear-wheels being fast to the'frame, a shaft secured to the othergear-wheel, shifting mechanism connected to the clutch-sleeve, wherebywhen the driven shaft has turned a certain number of revolutions it willbe automatically reversed, substantially as described.

4. The combination of a driving-shaft, a clutch-sleeve, two bevel-gearsloose on the said shaft and arranged to be clutched to said sleeve, asecond sleeve, a gear-wheel thereon meshing with both gear-Wheels of thedrivingshaft, two eccentrics on the second sleeve, a gear-wheel havinglugs on each eccentric, said lugs interlocking so that they will turntogether, two internal gear-wheels, of which one is fast to the frame, ashaft secured to the other internalgear-wheel, a bevel-pinion on thesaid shaft, a bevel gear-wheel meshing with the pinion, two lugs on thebevel-wheel, two arms on the shaft of the said gear-wheel, alug on oneof said arm s, a disk, alug thereon, the parts being arranged so thatthe lugs on the gear-wheel will engage with one arm and that arm willengage the other arm, and the second arm will engage the lug on thedisk, with a rack-bar connected to the disk, a segment gearing with therack-bar and having arms, and a shifting lever actuating theclutch-sleeve and actuated by the segment, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses. A

GEORGE II. BURPEE.
